While developing a web interface to read the MKU UP 2424 B status remotely, I noticed something strange in respect to the values returned via the data port for forwarded and reflected powers 0 to 255 range)
First trials with a Potty antenna resulted in a VSWR > 6 (!)
I then connected a 50 Ohm dummy load, and it was even worse.
Up-converter returned 146 for Forward and 94 for Reflected which (if my calculations are correct) would result in a VSWR of 9.1.
Has anyone experienced the same?, or is there something I do not understand?
